Example 3: This example shows how the cost of a call is calculated if the call spans over

multiple time bands:

Assume a Cost Group, "CG Local" is configured with two time bands, as shown below:

Assume that the call duration is 10 minutes, occurring between 16:55 and 17:05. In other

words, the first 5 minutes occurs in time band "TB1" and the next 5 minutes occurs in "TB2",

as shown below:

The device calculates the call using the time band in which the call was initially established,

regardless of whether the call spans over additional time bands:

Total call cost = "TB1" Connection Cost + ("TB1" Minute Cost x call duration) = 2 + 1 x 10

15.5.2 Configuring LCR

To configure LCR, perform the following main steps:

Enable LCR - see Configuring a Gateway Routing Policy Rule on page 539 (for Gateway)

and Configuring SBC Routing Policy Rules on page 730 (for SBC).

Configure Cost Groups - see 'Configuring Cost Groups' on page 285.

Configure Time Bands for a Cost Group - see 'Configuring Time Bands for Cost Groups' on

Assign Cost Groups to outbound IP routing rules - see 'Assigning Cost Groups to Routing

Rules' on page 288.

The Cost Groups table lets you configure up to 10 Cost Groups. A Cost Group defines a fixed call

connection cost and a call rate (charge per minute). Once configured, you can configure Time

Bands per Cost Group.

The following procedure describes how to configure Cost Groups through the Web interface. You

can also configure it through ini file (CostGroupTable) or CLI (configure voip > sip-definition least-

cost-routing cost-group).

To configure a Cost Group:

Open the Cost Groups table (Setup menu > Signaling & Media tab > SIP Definitions folder
